| dc.description.abstract |
A new spatially resolved optical technique to measure temperature was developed using
two-photon absorption of xenon. This experiment excited the 256 nm two-photon
transition of xenon by focusing the excitation source into a test cell at room temperature.
Two-photon absorption only occurs at the focus of a laser beam; therefore a point
measurement technique was possible. The spatial resolution for this experiment was
approximately 0.6 mm; however, this technique enables higher resolution depending on
the focus of the laser beam. Two-photon absorbance versus xenon number density was
determined experimentally and used to validate a theoretical model created in MATLAB.
This technique was designed primarily for two non-reacting flows: the vortex tube and
the pulse tube. A case study for measurement in a vortex tube was presented; however,
applying this technique to a pulse tube will be similar. |
